You need a Din 300 or Scuba Yoke Assembly depending on the fitting on the Scuba tank.http://www.airtanksforsale.com/HAve you watched any of the filling from a HPA tank such as this one?http://www.gatewaytoairguns.org/GTA/index.php?topic=34730.0
Tom,I would look more towards the SCBA tanks 88 cubic foot if possible. Your tank is normally one of the most expensive pieces of equipment for a marauder, etc set-up. A brand new Whole Hog from Air hog will run you around 780 bucks brand new! But then that tank is good for 15 years so it is one of those save up sacrifices that is well worth it in the long run and gives you 4500psi on hand whenever you need it which is plenty of fills! You can also find good deals at times on ebay but be very careful and ensure that the tank is still serviceable before buying!Matt
Hi Tom If you can't find a place that can fill a scba tank you may want to consider the benjimin carbon fiber 4500 psi tank or the ninja tank 4500 tank.They are smaller but a paintball shop should be able to fill them.i would ask around before ordering them.Hope this helps Dave
Fire Departments can fill to 6000 psi.Aloha...
Ha! Well, I'd go to the town over then.
